The Japanese government has strongly protested China's failure to stop a new wave anti-Japan protests.

A Foreign Ministry statement released Saturday accuses China of doing nothing about the violent protests even though authorities knew about them in advance.

At least 10,000 demonstrators took to the streets of Shanghai earlier Saturday, with some throwing stones and bottles at the Japanese consulate. Others smashed windows and signs at Japanese restaurants.

Thousands people protested in the eastern cities of Hangzhou and Tianjin.

The demonstrators denounced Japan's bid for a permanent seat on the United Nations Security Council and condemned Japan's approval of new school textbooks, which, they say, minimize Japan's wartime atrocities in China.
